Colorectal cancer (CRC) is a highly prevalent malignancy worldwide, and its substantial heterogeneity urgently calls for more precise prognostic biomarkers. This study integrated bibliometric and bioinformatics approaches to systematically delineate the RNF research landscape, construct a CRC prognostic risk model based on the RNF43 interaction network, and explore its association with the tumor microenvironment (TME). Bibliometric analysis revealed that publications in the RNF field have increased rapidly (compound annual growth rate of 28.5%), with research hotspots shifting toward CRC and other diseases, and RNF43 emerging as a core frontier. Analysis of TCGA and GTEx data showed that RNF43 was significantly overexpressed in CRC. Through the STRING database, RNF43-interacting proteins were screened and intersected with CRC-related targets, identifying RNF43-mediated core CRC targets (RNF43, FZD1, FZD5, FZD8, LGR4, LGR5, RSPO1, RSPO2, RSPO3, RSPO4, and AKAP8L). Based on the TCGA-COAD+READ cohort (n = 541), these core targets were incorporated into LASSO regression analysis, resulting in a risk score model comprising LGR4, RSPO4, AKAP8L, and RNF43. In the training set (TCGA-COAD+READ), the high-risk group exhibited significantly shorter overall survival (OS), with AUCs of 0.61, 0.60, and 0.61 for 1-, 3-, and 5-year OS, respectively. The model was externally validated in the GSE39582 cohort (n = 579), although the AUC values remained modest. Multivariate Cox regression analysis demonstrated that the risk score, age, and tumor stage were independent prognostic factors for OS in CRC patients; a nomogram integrating these three factors showed acceptable calibration. TME analysis revealed that the high-risk group displayed a \"pro-inflammatory phenotype under immunosuppression\": increased infiltration of stromal components, increased CD8⁺ T cells but decreased CD4⁺ memory T cells, unexpectedly elevated M1 macrophages, and no significant difference in overall immune score. This complex imbalance pattern-characterized by increased effector cells, loss of memory cells, and pro-inflammatory polarization accompanied by potential functional suppression-suggests a possible mechanism of immune evasion. In conclusion, this study is the first to adopt a strategy combining \"macro-level bibliometric insights\" with \"micro-level bioinformatics mining,\" systematically delineating the research trajectory of the RNF family and successfully constructing and validating a CRC prognostic risk model based on the RNF43 interaction network.

Approximately 19% of CRCs diagnosed in adults younger than 45 years exhibit MMRD by immunohistochemistry (IHC). In pediatric tumors, MMRD accounts for 39% of high-grade gliomas (HGGs) and 44% of CRCs, likely reflecting the increased prevalence of constitutional MMRD (CMMRD) in this highly consanguineous population. However, the molecular characterization of MMRD-associated tumors in the Middle East remains limited. We analyzed 14 Jordanian patients (< 45 years) from 12 families with clinical or IHC evidence of MMRD, including four HGGs and 11 CRCs; five patients were children.

However, the mechanisms integrating epithelial-mesenchymal plasticity (EMP), anoikis resistance, and cancer stemness remain incompletely defined. Primary cilia are spatially restricted signaling compartments whose assembly and function vary with cell state, tumor lineage, and pathway context. This review evaluates how primary cilia may connect these metastatic adaptations by organizing responses to microenvironmental cues. Evidence from mammary epithelial and breast cancer models links selected EMP states to increased ciliogenesis and to Hedgehog-GLI or cilium-dependent GLIS2 signaling, which may support stem-like properties and treatment resistance. Ciliary signaling can also intersect with adhesion, cytoskeletal, and pro-survival pathways involved in survival after detachment. However, these downstream networks are not specific to primary cilia, and direct evidence that ciliary signaling causes anoikis resistance remains limited. Hypoxia, matrix stiffness, and receptor-mediated signals may further modify ciliary function and cellular plasticity, but their effects are tumor- and model-dependent. Overall, primary cilia should be viewed as context-dependent organizers rather than universal drivers of metastatic behavior. Future studies should define ciliary status alongside EMP state, anchorage-independent survival, and functional stemness to determine when cilia constrain tumor progression, support malignant signaling, or provide therapeutically actionable dependencies.</p>","PeriodicalId":11148,"journal":{"name":"Discover.

In glioma cells, LAMP2 was upregulated, and lentiviral knockdown of LAMP2 significantly inhibited cell proliferation, migration and invasion, while increasing apoptosis.
